1 For SRU responses allow Content-Type application/xml as well as text/xml.
5 Fixed bug in character set conversion of BER strings. Bug introduced
10 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
12 For OID class, use oid_class consistently.
14 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
17 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
18 character set for bibliographic information interchange". By Giannis Kosmas.
20 Added documentation on new OID API.
24 Changes to generic frontend server interface: added new member
25 'query_charset' for bend_initrequest structure. A backend init handler
26 should set this member to its native character set for query terms.
27 When defined, the frontend server logic will announce this character set
28 to a client if the negotiationModel bit is set by the client. All server
29 implementors are encouraged to specify this. If a backend server does not
30 specify this a warning is issued using yaz_log(YLOG_WARN,..).
32 Added CCL utility to remove terms (stop words) from resulting RPN
33 tree. This is handled by functions with prefix ccl_stop_words_ .
35 New ZOOM C option, "rpnCharset", which allows client-side conversion of
38 Clean-up the CCL API. Moved some internal structures from ccl.h to
39 private header cclp.h. Changed ccl_parser_create so that a Bibset must
40 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
41 This is replaced by ccl_parser_find_str which takes a string instead.
43 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
44 libyaz.la is the core of YAZ except the generic frontend server and
45 does not depend on POSIX threads anymore. libyaz_server.la is the
46 generic frontend server facilities and uses POSIX thread functionality
47 if available. The libyaz.la no longer depends on POSIX threads because
48 the number of global structures is limited. NMEM no longer re-uses blocks
49 between threads ; it simply free's memory immediately but allocates in
50 "large" chunks as usual. We don't expect any performance penalties
51 because of this. The yaz_log system is still using a global log_level so
52 caution must be taken when modifying it with yaz_log_init_.. +
53 yaz_log_mask_str. This, however, should not cause any trouble because
54 these functions are called during initialization of application code
55 anyway. `yaz-config --libs server` returns libs for server applications;
56 `yaz-config --libs` returns libs for non-server applications.
58 New OID database - with public definitions in oid_db.h. Removed old OID
59 database including the head oid.h and definitions such as enum oid_value
60 and struct oident. The new OID database uses the same string names as
61 before but the 'protocol' is gone. There are now only two representations
62 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
63 converts from string to OID; functions with prefix yaz_oid_to_string
64 converts the other way.
66 Change to emit_term() in CQL-to-PQF query translation: when a term has
67 the /regexp relation modifier, do not process it for leading and
68 trailing "^" and "*", which have quite different meanings in regular
71 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
72 write handlers no longer carries a 'last' parameter. This will make
73 yaz_iconv flush "less" characters. A flush is performed by call to
74 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
76 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
77 removed, because function yaz_query_to_wrbuf does the same.
79 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
80 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
82 Deprecated MARC utility functions removed.
84 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
87 Branch split: YAZ_2_1_55_branch
91 Fix to ZOOM-C so that transparent reconnection is properly handled on
92 connections that are in asynchronous mode.
94 Fixed compilation on OpenBSD 4.0.
96 Large strings in GRS-1 records are now properly displayed in yaz-client.
98 Added character conversion support for "advancegreek"; based on patch from
101 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
102 sequence is met. Before the error was not set so it would be unknown.
104 Adjust yaz-marcdump MARC reader so that it skips until record separator
107 --- 2.1.52 2007/03/07
109 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
110 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
111 fd_set structure used as a bitmask for the FDs to be selected on.
113 Using ACX_PTHREAD macro to check for POSIX threads.
115 Fixed have-vsnprintf check.
117 --- 2.1.50 2007/02/23
119 Fixes for configure on BSD. Bug #900.
121 Added snprintf/vsnprintf wrappers for systems that don't have
122 limits (heavens forbid).
124 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
125 created before all previous tasks were completed and removed from the
126 task queue, the new task could be removed by a mistake.
128 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
130 Implemented pass-through CQL-to-PQF conversions. Bug #861.
132 Fixed bug #832: Problem with MARC/charset in yaz-client.
134 Fixed bug #668: save command line history for yaz-client.
136 Fixed bug #830: pkg-config support.
138 --- 2.1.48 2007/01/23
140 Extended ZOOM result set options with two options that may be read by
141 a client: resultSetStatus and presentStatus with values as specified for
143 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
145 Fixed bug #827: Using SSL fails on Debian etch.
147 Fixed bug #826: Weird looking chars for set of MARC records.
149 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
150 that is treated as an ItemOrder with itemRequest being an XML document
151 external. The value of "doc" is the content.
153 Extended the GFS search facility. New member of bend_search_rr
154 'estimated_hit_count' signals that hits is known to be an estmate
155 (higher or lower than real hit count). New member 'partial_resultset'
156 signals that the search was partial (hit count is lower or equal than
157 real hit count). For Z39.50, the information is stored in resultSetStatus
158 member of SearchResponse APDU. For SRU, the information is signalled
159 via SRU diagnostic 59: "Result set created with valid partial results
162 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
164 --- 2.1.46 2007/01/13
166 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
168 Added ZOOM_connection_peek_event.
170 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
171 the following new functions:
172 ZOOM_event_nonblock, ZOOM_connection_process,
173 ZOOM_connection_get_{socket,mask,timeout},
174 ZOOM_connection_fire_event_{timeout,socket}.
175 The existing blocking event handler, ZOOM_event, is a wrapper for the
176 + blocking ZOOM_event_sys_{poll,select}.
178 Implemented function ccl_xml_config which parses XML version of CCL
179 configuration (bug #798).
181 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
183 Added timings utility (yaz/timing.h)
185 --- 2.1.44 2007/01/03
187 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
190 Fixed bug #779: Rotation of apdu.log fails.
192 Fixed for character set conversions:
193 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
194 Honor G1 set in MARC-8 decoding.
196 --- 2.1.42 2006/12/17
198 Fixed bug #775: char conversion does not handle Alternative UTF-8
201 Implemented function yaz_marc_read_line which parses MARC line format
202 records. There is a wealth of formats out there. So far, this function
203 reads line records produced by yaz_marc_write_line.
205 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
206 more generic and easier to remember(!) options: -i format and -o format
207 which specifies input format and output format respectively - where
208 format is one of "marc", "marcxml", "line", "marcxchange".
210 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
211 does not print anything except warnings for records.
213 For yaz-marcdump, added support for MARC split into files (-s) with a given
216 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
217 spec, at http://www.loc.gov/standards/sru/record-update/
218 This has changed the binary layout of the following structs:
219 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
220 bend_update_rr . Patch by Ko van der Sloot.
222 Added GFS utility function bend_assoc_is_alive which returns 1 if
223 association is still alive (client is connected); 0 otherwise (client
224 closed connection). This allows busy servers to stop working for
227 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
228 been a separate piece of software. This version of ziffy has been modified
229 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
231 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
233 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
234 Client code may now interrogate options such as "init_opt_sort" to
235 find out whether the server claims to support various options.
237 --- 2.1.40 2006/11/27
239 Added utilities yaz_{set,get}_esn to set/get element set name from
242 Removed the build of libyazthread.la. The libyaz.so is the threaded version
243 of YAZ and has been so since YAZ 2.1.10.
245 Implemented ZOOM_record_error which returns error information for
246 record (surrogate diagnostic).
248 --- 2.1.38 2006/10/31
250 Updates for SRU Update by Ko van der Sloot:
251 1. Changed name from "operation" to "action"
252 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
253 versions in the code, marked as 'backward compatible'.
254 3. Added diagnostics for SRU Update.
256 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
258 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
260 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
262 For GFS, fixed problem with SRU diagnostic 'First record position out of
263 range' being issued for 0 hits.
265 zoomtst10 part of Windows Build.
267 --- 2.1.36 2006/10/13
269 Implemented yaz_filepath_comp which splits a path into file path
270 components (required by Zebra 2.0.3+).
272 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
273 BSD inspired license until now so this should not have any real impact on
274 anybody. See http://www.opensource.org/licenses/bsd-license.php
276 Fixed bug #687: Missing log lines.
278 Fixed bug #678: CQL to PQF translation does not preserve double-quote
281 Fixed bug #689: SRU diagnostics to be added.
283 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
284 whether a connection is idle (no more work do do).
286 --- 2.1.34 2006/10/04
288 Change type of optval from long to int for invocation of setsockopt with
289 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
291 Added support for specifying the max log file size for the Generic
292 Frontend Server. The size is given with option -r.
294 --- 2.1.32 2006/09/21
296 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
298 --- 2.1.30 2006/09/17
300 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
303 Fixed bug in Generic Frontend Server that could cause a server to stop
304 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
306 For the generic frontend server, the maximum record size is used as maximum
307 size of incoming packages (SRU + Z39.50). The value until was previously
308 only used in Z39.50 Init negotiation and, later, in a session controlled
309 sizes of records returned. This is controlled using -k option. It can be
310 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
312 --- 2.1.28 2006/09/04
314 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
317 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
319 New option for yaz-marcdump -lpos=value which allows setting a portion
320 of MARC header to a certain value.
322 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
324 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
325 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
327 --- 2.1.26 2006/08/15
329 Fixed problem with SRU mode type (soap, get, post) for yaz-client
332 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
334 --- 2.1.24 2006/08/08
336 Fixed MARC ISO2709 encoding routines to deal with character set
339 Minor changes to GFS logging. Database included in search request log
342 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
343 cached/multiple records.
345 Shared libraries are built by default on Unix+configure.
347 Changed cql2pqf transformation to use a different evaluation order. The
348 new order is: always, relation, structure, position, truncation, index
349 and relationModifier. Old order was: always, relation, relationModifier,
350 structure, index, position, truncation. Note that the the latter ones
351 override former ones for identical attributes.. The new scheme means that
352 it is possible to override any existing attribute with a relationModifier.
353 And also that it is possible to override everything for the index rule
354 (except the ones listed in relationModifier). No order is perfect but this
355 one, we believe, covers more real cases.. The "always" should have been
356 called "default", since the attributes there can be overridden with all
359 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
360 compilation phase, but also for yaz-config --cflags output. This allows
361 us to have public headers with Libxml2 stuff in them . It should also,
362 eventually, make Libxml2 checks redundant in packages using YAZ, such
365 --- 2.1.22 2006/06/15
367 Changed SRU update structure bend_update_rr so that SRU diagnostics are
368 stored in uri, message and details.. Previously diagnostics were stored
369 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
370 compatibility.. but he's probably the only one affected, so.
372 Added support for CCL, compiled on the client side, in ZOOM-C. This
373 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
374 input; the resulting query objects can be used for for searching with
375 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
377 YAZ' configure searches for OpenSSL by default.
379 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
380 SL_CTX_use_certificate_file. See
381 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
382 for more info. Thanks to Ko van der Sloot.
384 --- 2.1.20 2006/06/02
386 Bug #600: SRU GET, POST support for yaz-client. Introduced
387 command 'sru' which selects method SOAP/GET/POST.
389 Allow missingValueAction to be specified for the sortspec string -
390 function yaz_sort_spec. By default, the missing value action is null.
391 Use ! to specify "abort". Use = followed by stringvalue to specify default
394 Ensured that Present-handler (if defined) is called in GFS before any call to
395 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
396 searchRetrieve requests.
398 Documentation for YAZ is now based on the Docbook XML/XSLT using
399 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
400 is no longer depending on jade/openjade or docbook-to-man scripts.
401 PDF is no longer part of the distribution - but can optionally be
402 made using DSSSL/jadetex or FOP.
404 Added retrieval handling support in Generic Frontend Server to support
405 conversion between MARC/XML as well as XSLTtransforms. See
406 etc/yazgfs.xml for an example.
408 Added Authentication support to Generic Frontend Server in SRU
409 mode. Authentication using HTTP Basic is supported, as is the use
410 of 'x-username' and 'x-password' parameters in the request itself.
412 Added support for a new character set MARC8s identical to MARC8 except
413 that it converts combined characters to single Unicode characters in the
414 Latin-1 range (when possible).
416 --- 2.1.18 2006/04/24
418 ASN.1 compiler 0.4: generates brief Doxygen file header for
419 generated .h/.c files.
421 Utility yaz_iconv now supports conversion to MARC-8.
423 New facilities for the MARC module. The reading - and writing of
424 content are separate methods for the yaz_marc_t handle. The following
425 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
426 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
427 format). Write functions have prefix yaz_marc_write_.. The existing
428 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
429 available. Removed support for OAI-MARC and simplexml (not the
430 simplexml from PHP5).
432 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
433 to be returned for this connection.
435 --- 2.1.16 2006/03/31
437 Allow multiple languages and charsets to be specified with
438 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
439 negcharset iso-8859-1,utf-8
441 Translation of proximity nodes from CQL into PQF now works.
443 Moved to automake 1.8, 1.9.
445 Added function yaz_log_set_handler which allows a log handler to be
446 installed. This handler will be called for all log messages. Output
447 to file is also produced; but that can be disabled by passing NULL
448 fname to yaz_log_init_file.
450 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
452 For SRW (including GFS), accept application/soap+xml as content-type
455 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
456 produces NO stylesheet reference even if a default stylesheet is specified
459 --- 2.1.14 2006/03/14
461 Updated Windows package to include yazd.dll + yazd.lib for the
462 Development component.
464 If the environment variable YAZ_LOG is set, then it is used as a
465 string indicating the default level of logging to use if not
466 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
467 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
468 used as before. So, for example, to omit warnings from YAZ logging,
471 cql_transform() now map structure and other attributes before indexes,
472 so that index-specific structures and other attributes can override
473 defaults. So now a combination of mapping specifications such as:
475 index.dc.date = 1=date-modified 4=5
476 does the right thing.
478 cql_transform() now also respects the "always" mapping specification,
479 which establishes an initial set of attributes to be used for all
480 terms except where overridden by more specific attributes associated
481 with the index, relation or modifier.
483 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
484 which mode to use; one of "post", "get" or "soap" (SRW, default).
486 Fixes for yaz_iconv routines: changed trie-based character set conversions
487 to use only non-negative values for bit fields due to Sun's C compiler not
488 supporting negative values.
490 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
491 sequences where not read correctly. Fix by Rustam Usmanov.
493 Updated win/makefile to use options, settings which makes things
494 compile with VS C 2005.
496 --- 2.1.12 2006/02/01
498 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
500 In ZOOM socket code, use select instead of poll on MacOSX.
502 ZOOM-C now support client-side compilation of CQL into RPN that is
503 sent to the server, enabling CQL to be used against all Z39.50
504 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
505 ZOOM_query object, and submit it using ZOOM_connection_search().
506 The CQL-to-RPN translation uses a configuration file, the name of
507 which must be specified in the Connection's "cqlfile" option.
509 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
510 function, which takes as its start-term parameter a ZOOM_query object
511 (which may have had either CQL or RPN set into it).
514 --- 2.1.10 2005/11/29
516 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
517 GFS to support this as well. Backend handler, bend_srw_update, does the
518 update work. Code contributed by Ko van der Sloot.
520 Allow retrieval of Search Result-1 information in ZOOM by the use of
521 options that are attached to a result set. ZOOM documentation updated
524 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
525 UTF-8 conversion. Patch by Raj Patel.
527 Added option -m to GFS to control formatting of timestamps in log file.
529 Added 'exit' as synonym for 'quit' in yaz-client
531 Added support for specifying SRW resultSetId + resultSetIdleTime in a
532 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
533 for the new members. Patch by Ko van der Sloot.
535 Added support for SRU POST. It is supported for content-type
536 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
538 Do not build the separate Multi-threaded (MT) library libyazthread.la.
539 Instead make the library libyaz.la multi-threaded. Threading as a whole
540 can still be disabled by configure option --disable-threads. Previosly,
541 with older GLIBCs there were problems with MT libs under Apache. This
542 has now been fixed a long time ago.
544 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
547 CQL module modified to be case insensitive for relations/indexes/operations.
549 Fixed bug in CQL transform code: incorrect value relationModifieder
552 Added 'show all' command for yaz-client which retrieves all results
555 Added new yaz-client, xmles, which takes a (private) OID and
556 a document to be sent as an extended service request.
558 Describe new yaz-client commands wait_response and set_auto_wait.
560 Increase TCP/IP listener backlog from 3 (which I am guessing was
561 copied from the SunOS manual entry way back when) so SOMAXCONN, so
562 that the socket will queue as many incoming connections as it's able
563 to handle ongoing connections. In other words, it will never now
564 refuse a connection that it would be able to handle merely because
565 it's not got around to accepting() enough of the pending connections
566 yet. This is the behaviour anyway under Linux, where the listen()
567 argument is ignored; but not under BSD and on systems such as
568 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
569 YAZ-based servers should now be uniform across operating systems in
572 yaz-marcdump uses 64-bit file access on some systems. This is enabled
573 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
574 This allows yaz-marcdump to read large MARC batches (>2 GB).
576 Modified all YAZ source files - except the source which is auto-generated
577 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
580 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
581 corresponding to the existing *_setl() function. These allow option
582 values containing arbitrary valuues.
584 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
585 ZOOM_resultset_sort() in new applications. Its behaviour is identical
586 except that it returns an indicator of whether or not the sort
587 criterion was accepted (0 for OK, -1 for invalid).
591 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
592 MARC output rather than returning "new" buffer.
594 yaz-client warns about unknown init options.
596 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
600 Added support for SRW sort in Generic Frontend Server. Patch
601 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
602 sortKeys - or NULL if none is provided.
604 Fixed bug #307: It was impossible to specify indefinite/no timeout
605 for ZOOM_event. Special timeout value -1 now means indefinite timeout
608 Added support for multiple languages and charsets to be specified in
609 ZOOM. Each charset/language is separated by a blank. If negotiation is
610 in effect in init-response, Option
611 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
612 Code based on patch by Vasiliy Osadchuk.
614 Fixed bug #306: infinite recursion that occurred when calling
615 yaz_log_level_init as the first call (before other log level or
618 Fixed bug in scan handling in front end server: if preferred-Position-In-
619 Response was non-present, a NULL pointer referece was performed.
623 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
624 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
625 now defined for all those error codes. So instead of putting 109 in
626 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
627 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
629 Modified the yaz-marcdump utility to skip garbage bytes between MARC
632 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
634 Program yaz-client now exits and produces an error message if multiple
635 Z39.50 servers are specified on the command line (none or one allowed
638 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
643 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
645 Fixed bug #272: Preserve spacing for CCL terms.
649 Added support for virtual hosts and multiple backend servers for
650 the YAZ frontend server. The configution is XML based and
651 support specificition of CQL to RPN mappings and explain information.
652 See section "Virtual Hosts" in the YAZ manual.
654 Extended OPAC display utility. OPAC display utility renders
655 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
656 to supplement yaz_marc_decode_wrbuf.
658 Fixed a bug in MARC decoder that could caused it to crash for some
659 invalid MARC records. More diagnostics and warnings where added in
660 XML output (warnings, etc are stored in comments).
662 --- 2.0.34 2005/02/08
664 Fixes for UNIX domain sockets. Bug #261.
666 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
668 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
669 Added yaz_marc_subfield_str which defines subfield lead string which is
670 used in YAZ_MARC_LINE format. Default string is blank+$. Added
671 yaz_marc_endline_str which defines end of fields string used in
672 YAZ_MARC_LINE format. Default string is newline.
674 Experimental support for MarcXChange. This format can be produced
675 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
676 http://www.bs.dk/standards/MarcXchange.xsd
678 Added yaz-client commands scansize that sets maximum number of
679 entries to be returned by scan.
681 --- 2.0.32 2005/01/11
683 Added support for SRW scan in yaz-client and Generic Frontend Server.
685 * Added whereInList member to SRW Scan Term.
687 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
689 Fixed NMEM system to return aligned blocks on the smallest boundaries
690 that are suitably aligned for all possible types on the particular
691 architecture YAZ is being built for.
693 --- 2.0.30 2005/01/04
695 Fixed numerious warnings that was issued with newer versions of GCC.
697 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
698 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
701 Make YAZ Generic Frontend Server slightly faster.
703 Enhance (and reduce) logging for Generic Frontend Server.
705 Revert YAZ log system so that it flushes every write operation
706 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
708 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
709 instead of LOG_, due to name clash with syslog(3). LOG_ are still
710 present. New applications should define YAZ_USE_NEW_LOG=1 - this
711 will effectively disable old definitions.
713 --- 2.0.28 2004/11/09
715 Added yaz_log_time_format which specifies log format using
718 Added yaz_log_module_level which returns mask for a module. Value
719 is non-zero mask a if module is enabled; zero if disabled.
721 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
722 in include/yaz/cql.h.
724 Fixed bug #176: Dont throw diagnostics on empty SRU args.
726 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
728 Fixed bug #172: RPM builds does not enable SSL.
730 Doxyfile.in part of dist. Doxyfile generated by configure.
732 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
733 are given and the corresponding component does not exist.
735 Extend CCL documentation in YAZ reference. Describe r=r.
737 --- 2.0.26 2004/10/01
739 Fixed MARC->MARCXML conversion to properly deal with
740 fields, subfields, indicators having non-ASCII characters.
742 Fixed MARC->MARCXML conversion so that ASCII control characters
743 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
746 Added YAZ GFS support for conversion from Z39.50 surrogate
747 diagnostics to SRW surrogate diagnostics.
749 Bug fix: YAZ GFS did not return schema in explainResponse.
751 --- 2.0.25 2004/09/30
753 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
754 now converts recordSchema to elementSetName as well as schema URI.
756 Fixed bug in COMSTACK that prevented HTTP request packages from being
759 --- 2.0.24 2004/09/29
761 Added CCL facility r=r "range" which is similar to r=o "ordered" but
762 does not require white-space before and after the dash in a range, e.g.
763 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
766 Fixed a few AC_TRY_LINK configure tests that did not operate properly
767 due to new GCC removing "redundant" code.
769 Added yaz-client commands scanpos and scanstep that sets preferred
770 position and step-size for scan.
772 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
774 Added CCL utility ccl_qual_buf which parses one or more CCL
775 spec lines in a buffer.
777 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
778 of name and value - ignoring empty lines and comments.
780 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
782 Added odr_get_element_path which returns current element path for an
783 ODR handle. This utility is useful in error handling or user-defined
786 Added ODR_PRINT utility odr_set_stream which is is a more generic
787 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
788 to a write function and pointer to close function. The close function - if
789 non-NULL - will be called during odr_destroy.
791 Fixed bug in CCL parser where truncation char was not removed from
792 right side when truncation=both was in effect.
794 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
797 --- 2.0.23 2004/08/11
799 Fix buffer overrun in CQL parser when dealing with proximity (%).
801 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
802 to UTF-8/UCS conversion is now only based on codetables.xml.
804 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
806 --- 2.0.22 2004/08/06
808 Add support for more "commit changes" in ZOOM (uses Extended Services).
810 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
813 Yet another small fix for configure of SSL.
815 --- 2.0.21 2004/05/14
817 Fix SSL libs for configure when --with-openssl=DIR is given.
819 --- 2.0.20 2004/05/10
821 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
823 SSL comstack now uses yaz.pem certificate file on server side
824 by default. Certificate filename can be configured by calling
825 comstack function cs_set_ssl_certificate_file before cs_bind is used.
827 Fix bug regarding multiple calls to ZOOM_connection_connect.
829 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
831 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
832 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
834 ZOOM now allows inspection of X509 peer certificate for verification.
835 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
837 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
838 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
839 as "modular" but it simplifies things.
841 Added cs_get_peer_certificate to that returns peer X509 PEM.
843 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
844 NULL if SSL is unavailable.
846 Documentation about MARC decoding tools.
848 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
850 --- 2.0.19 2004/03/30
852 Rename CHANGELOG to NEWS to follow GNU style packing.
854 Fix bug with missing initialization of member in init_diagnostics.
855 This bug affects threaded version of GFS server.
857 --- 2.0.18 2004/03/20
859 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
862 Ensure zlib.dll is packed with Windows install.
864 --- 2.0.17 2004/03/17
866 Fix encoding of xsd:string to use text instead of CDATA.
868 Fix endless loop in CQL parser with unbalanced ".
870 Use a more compact way to store MARC-8 conversion tables.
872 --- 2.0.16 2004/03/16 Debian only
874 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
877 Update CQL parser to use new CQL 1.1 modifiers for booleans and
882 --- 2.0.15 2004/03/01
884 Another fix for decoding of XML packed records.
886 --- 2.0.14 2004/02/25
888 Fixes for Chunked encoding. White space not ignored after length spec.
890 Update NS and use default NS for SRW diagnostic elements.
892 --- 2.0.13 2004/02/23
894 Implement ZOOM_resultset_cache_reset which resets record cache.
896 Implement ZOOM_resultset_sort which sorts a result set.
898 Implement chunked HTTP transfer.
900 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
902 --- 2.0.12 2004/02/16
904 Added member 'schema' to bend_explain_rr structure so that backend
905 can specify explain record identifier. Defaults to Zeerex 2.0.
907 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
909 --- 2.0.11 2004/02/16
911 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
914 Added init command for yaz-client which sends "extra" init request.
916 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
917 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
919 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
921 Make ZOOM error code for "invalid query".
923 Fixed compilation for SSL which wasn't properly enabled for all platforms.
925 --- 2.0.10 2004/02/05
927 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
930 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
932 Added option -p <file> to make Generic Frontend Server to write PID file.
934 Added option -D to put Generic Frontend Server in background on its own.
936 Make ZOOM C recognize option "password". If unset, "pass" is used
937 (for backwards compatibility).
939 Fixed a bug in Generic Frontend Server that could make it crash if a
940 client sets characterSetNegotation bit, but didn't pass negotiation stuff
943 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
944 Must be issued before open, in order to be in effect.
946 --- 2.0.9-6 2004/01/12 Debian/Windows
948 Make the SRU server more picky WRT unknown params, etc.
950 Bug fix: ZOOM scan response didn't return displayTerm - when present.
952 New YAZ client command, options, that sets Z39.50 options.
954 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
955 options from a string of tokens (one token for each option bit).
957 Update SRW diagnostic code messages.
959 --- 2.0.9-5 2004/01/07 Debian/Windows
961 Handle user defined stylesheet for SRW/SRU.
963 --- 2.0.9-4 2004/01/06 Debian/Windows
965 Fix bug in decoding of Content-Length.
967 --- 2.0.9-3 2004/01/06 Debian/Windows
969 Fix a bug with decoding of XML packed records.
971 --- 2.0.9-2 2004/01/05 Debian only
973 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
975 Fix bug in SRW/SRU diagnostics decoding.
979 Fixed bug in Generic Frontend Server which could drop records exceeding
980 preferred message size. Reported and fixed by Irina Dijour.
982 Fixed calculation of package size for structured records in Generic
983 Frontend Server. Reported and fixed by Irina Dijour.
985 Fixed namespace for SRW/SRU diagnostics.
987 Fixed SEGV in yaz-client that occured for HTTP connection errors.
991 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
992 this version is incompatible with version 1.0 and older YAZ SRW/SRU
995 CQL changes to reflect recent changes to the specification:
996 * Documentation talks about context sets instead of index sets.
997 * Documentation talks about indexes instead of qualifiers.
998 * The CQL-to-PQF transformer's configuration file now uses
999 "index.set.name = <attributes>" instead of the old form
1000 "qualifier.set.name = <attributes>". (Both forms are still
1001 understood but the latter is deprecated.)
1002 * CQL terms with no explicit index specified are now interpreted as
1003 cql.serverChoice instead of srw.serverChoice (which of course
1004 behaves exactly the same.)
1006 --- 2.0.7 2003/12/16
1008 MARC conversion can now generate ISO2709 output in another
1009 character set. yaz-marcdump uses this facility if you invoke it
1012 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1013 functions from there can be used from C++.
1015 --- 2.0.6 2003/12/04
1017 Frontend server now transfers memory from decoded packages to stream
1020 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1021 references to show up.
1023 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1024 the ZOOM Abstract API. The older names for the same options are still
1025 also supported for the benefit of old applications.
1027 ZOOM-C supports "implementationId" and "implementationVersion" options
1028 to go along with "implementationName". These allow the user code to
1029 specify identification strings to be sent to servers.
1030 Add OID for the new ExtLite attribute set.
1032 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1033 as requested/supplid by Ere Maijala <ere@atp.fi>
1035 For generic frontend server, reverse the order of
1036 "toolkit-supplied / application-supplied" strings sent as implementationId,
1037 Name and Version. Also, remove the spaces around the slash. This brings
1038 the GFS in line with the behaviour of ZOOM-C on the client side.
1040 Add function ZOOM_scanset_display_term.
1042 yaz-client shows scan displayTerm if present.
1044 Utility yaz-iconv is now installed by default along with the man page
1047 Extend configure check for OpenSSL to use pkg-config where available (such
1050 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1051 server to specify uid/gid/mask for socket using the format
1052 unix:[user=uid,][group=gid,][umask=mask,]file=path
1053 If file= is omitted the existing format is assumed, e.g.
1055 in which case the mask is 0666 (rw for everybody).
1057 Major restructure of YAZ source. All source in libyaz is in src directory.
1058 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1059 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1061 Added man page for utility yaz-marcdump (used to be called marcdump).
1062 yaz-marcdump is installed by 'make install'.
1064 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1065 of incoming package failed.
1067 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1069 Change prototype of odr_perror: add const to message string.
1071 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1073 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1074 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1075 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1076 DNS lookup. There should not be any compatibility problems with this
1077 assuming that blocking=1 or 0 is used.
1079 Fix bad reference in UNIX comstack in function cs_addrstr.
1081 Fix for compilation on AIX.
1083 The generic front-end server (server/seshigh.c) now supports returning
1084 Init diagnostics to the client in User-information-field, in
1085 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1088 --- 2.0.4 2003/09/04
1090 Allow any CQL relation (not just all,any,exact,scr).
1092 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1093 that features the same UI.
1095 Implemented command update0 in YAZ client which is equivalent to
1096 update but uses old of Ext Update ASN.1.
1098 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1099 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1100 Previously no OID was used for this info.
1102 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1103 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1104 returns 'malformed search term' otherwise.
1106 SortResponse member resultCount now set to NULL in sort handler of
1109 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1112 Add three new utility functions for translating OIDs between various
1113 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1114 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1115 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1116 char *oid_to_dotstring(const int *oid, char *oidbuf);
1117 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1119 Reverted modifications for ES Update definition for z_IU0Update
1120 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1121 is back to YAZ 2.0.2.
1123 String value attributes for CCL parser.
1125 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1126 which their FirstSearch server returns in Init responses, sometimes
1127 carrying useful diagnostic information when Init fails. This has the
1128 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1129 "z39.50/oclcui.asn", where its definition is somewhat different from
1130 what OCLC document on their web-site, as required to interoperate with
1133 Support for anonymous authentication in yaz-client. Use the command
1136 * Fix the OID of the Index Data-local "admin" Extended Service from
1137 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1138 the 1000, which indicates a locally-defined OID, was a mistake.
1140 --- 2.0.3 2003/06/20
1142 Fix CCL directive @case handling so that it affects string match for
1143 both CCL keywords and qualifiers.
1145 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1146 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1147 Decoder has been updated with ASN.1 changes as listed in
1148 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1149 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1150 z_IUUpdate, remains unchanged.
1152 ZOOM_record_get may now return a record in a specific character set.
1153 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1154 "from" is the character set of record as returned by target. "to" is
1155 the character set to be returned. If omitted, "to" is UTF-8.
1157 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1159 New ODR utility, odr_getelement, which returns name of element for
1160 which encoding/decoding failed.
1162 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1163 in cases where a required element was omitted.
1165 Bug fix: some MARC8 sequences were not converted.
1167 New ZOOM option "step" which specifies number of records to be
1168 retrieved in one chunk. Used in conjunction with "start" and "count".
1170 SRW support for yaz-client. Use scheme http: to use it, e.g.
1173 yaz-client no longer does (un)intelligent character set conversions
1174 by default. Can be enabled with charset and marc_charset commands.
1176 xmalloc trace fix for 64-bit systems such as DEC alpha.
1178 Solaris 2.6 compile fix.
1180 New function, cql_strerror() translates SRW error codes, as returned
1181 by cql_transform_error(), into human-readable English strings. Used
1182 in yaz-client diagnostics when appropriate.
1184 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1185 converts it into a type-1 query which is sent to the server. This
1186 makes CQL available for use with all Z-servers, as opposed to the tiny
1187 minority that can handle CQL queries themselves.
1189 --- 2.0.2 2003/04/28
1191 New Debian package layout similar to the Redhat Package layout.
1193 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1194 and search result respectively.
1196 --- 2.0.1 2003/04/25
1198 Redhat package is now several packages: libyaz (runtime libraries),
1199 libyaz-devel (development and documentation, and yaz (utility programs).
1200 Package spec file by Morten Bøgeskov.
1202 New member 'schema' in struct bend_fetch_rr which the name of requested
1203 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1204 handler MAY set this to reflect the schema of the returned record.
1206 New member 'display_term' in struct scan_entry. GFS now sets member entries
1207 and allocates scan entries to be filled by user scan handler. In previous
1208 version, entries member was allocated by the scan handler. That still works,
1209 but the GFS will ignore member display_term - assuming it was NOT set by
1210 the handler. The fact that the GFS now allocates the entries both allows
1211 for new members and makes a scan handler easier to write.
1213 Fix CQL lex buffer overflow.
1215 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1216 SRU default recordPacking is string.
1218 SRU protocol support for frontend server.
1220 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1222 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1224 Added scan for the ZOOM shell (zoomsh).
1228 * String Identifers for Schemas (Amendment 5).
1229 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1230 Old definition for schema
1231 Odr_oid *schema; /* OPT */
1236 Z_InternationalString *uri;
1237 #define Z_Schema_oid 1
1238 #define Z_Schema_uri 2
1241 * resultCount parameter to Sort Response (Amendment 1).
1242 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1244 Support for SRW 1.0 over HTTP. This is an optional feature and
1245 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1248 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1249 on the same port. SRW SearchRetrieveRequests are mapped
1250 to bend_init,bend_search,bend_fetch,bend_close.
1252 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1254 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1255 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1257 ZOOM connections are SRW based if schem http is used for hostname
1258 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1259 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1261 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1262 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1263 distance=n, order=true/false, relation=le, prox unit=word. If
1264 n is omitted, distance 1 is used.
1266 Fixed problem with C compiler include path in wrong order.
1268 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1269 on Solaris. Patch from Ko van der Sloot.
1271 New MARC decode API. All new functions operate on a yaz_marc_t
1272 handle. The most important new functions are: yaz_marc_create,
1273 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1274 decode and destroy respectively. Decoder can produce formats
1275 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1276 include/yaz/marcdisp.h.
1278 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1279 to UTF-8, UCS-32, wchar_t or Latin-1.
1281 * Prototypes for yaz_iconv_-functions moved to separate header
1282 include/yaz/yaz-iconv.h.
1284 Make a few private functions 'static' in unix.c. This prevents
1285 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1287 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1288 are set when Init Response is received.
1290 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1291 but returns diagnostic set as well.
1293 New function yaz_strerror which is a portable wrapper for
1294 strerror/strerror_r/GetLastMessage.
1296 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1297 is returned for MARC. If type is "oai", then OAI MARC is returned.
1299 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1302 --- 1.9.2 2002/11/26
1304 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1306 Fix bad race conditions on SIGTERM and terminate gracefully in
1309 Move retrieval (data1) module to Zebra since nobody seems to be
1312 Add GRS-1 render for ZOOM using same format as yaz-client.
1314 --- 1.9.1 2002/10/05
1316 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1318 Fix broken ESpec handling in data1 module.
1320 SGML reader parses comments and makes them part of the data1 tree.
1322 Added several type casts so that YAZ compiles as C++ code.
1324 ZOOM didn't handle PDU encoding failures properly.
1326 Added more Bib-1 diagnostics (approved extensions).
1328 GNU configure: better check for iconv.
1330 More portable use of accept, getpeername. Check for socklen_t. Use
1331 int/size_t if socklen_t is not defined.
1335 PQF parser rejects bad queries - including those with extra
1336 characters in them. PQF parser used to silently ignore that.
1337 Cleaner API for PQF added, which allows you to get detailed
1338 error information for bad queries (see yaz/pquery.h).
1340 Fixed bug in ZOOM_record_get for type "database".
1342 Implemented mini iconv library supporting conversions between
1343 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1345 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1347 --- 1.8.9 2002/08/20
1349 Fixed ZOOM C record cache so that preferredRecordSyntax and
1350 elementSetName is used to check for already fetched records.
1352 --- 1.8.8 2002/08/02
1354 Added three members in bend_initrequest structure to facilitate
1355 character set negotiation.
1357 Fixed a bug in frontend server that could cause indefinite
1358 loops under rare conditions.
1360 Revised character set utilities (charneg.h) so that encoding
1361 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1363 For PQF, directive @term <type> sets term type for Scan/Search.
1364 Here <type> is general, string, numeric, null. The term type
1365 is inherited - just like @attr.
1367 New call odr_set_charset that sets character set conversion for
1368 international-strings on a ODR stream. Prototype is:
1369 int odr_set_charset(ODR o, const char *to, const char *from);
1370 The InternationalString is still represented as C string in YAZ
1371 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1372 won't). On the protocol level, you can use any encoding.
1374 Support for UNIX sockets in ZOOM.
1376 Solaris recv sometimes returns errno == ENOENT. It is treated as
1377 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1379 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1380 both client and server. Code by Morten Bøgeskov.
1382 --- 1.8.7 2002/05/22
1384 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1385 that they can be used directly from Visual Basic. You must recompile
1386 your windows APP if you're using ZOOM.
1388 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1389 Commands "lang" and "charset" sets language and character set respectively.
1390 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1391 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1393 Attributes from multiple CCL fields may be OR'ed rather than merged
1394 using directive "@field or". Fields are still merged by default -
1395 equivalent to "@field merge".
1397 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1400 Fixed bug in zget for parameter ExtendedServicesResponse.
1404 --- 1.8.6 2002/03/25
1406 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1408 Client displays USR.1:SearchResult-1 (hits per term).
1410 Additional Search Info for search in Generic Frontend Server.
1412 Fixed CCL parsing of "field=s".
1414 WIN32 installer - using the excellent NSIS software from nullsoft.
1416 Fixed CCL parsing of "field = - <number>".
1418 Added function yaz_marc_decode that decodes MARC for line mode
1419 display or XML (similar to that used by JZKit).
1421 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1422 Z39.50. But ISO/ILL was, however.
1424 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1425 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1427 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1428 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1430 --- 1.8.5 2002/02/03
1432 New YAZ client features: Command completion and new commands:
1433 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1434 Code provided by Jacob Poulsen.
1436 New call oid_trav, that visits all registered OIDs via callback.
1438 Function ZOOM_record_get now returns const char pointer rather than
1439 void pointer. It saves a lot of type casts.
1441 For YAZ client, command "auth" now allows you to set authentication
1442 in IdPass style. It is enabled when three tokens are given - order
1443 is user, group and password.
1445 Fix memory leaks in MARC record handling for ZOOM.
1447 New option for YAZ client, -k <kilobytes> that sets
1448 maximum record size. Similar to -k option for generic frontend
1449 server and yaz-ztest.
1451 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1453 Prefix query parser reports "fail" when bad attribute set is given.
1455 Fix in MARC decoder. Proximity logging. Fix for attribute set
1456 in scan handler for server. Patches by Shigeru Ishida.
1458 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1461 Configure option --with-openssl=<dir> now works when a directory is
1462 specified. Patch provided by Morten Bøgeskov.
1464 New option for YAZ client, -u <auth>, that sets authentication.
1466 ZOOM fix: error information was sometimes "missing", since error
1467 was cleared/reset too when it shouldn't.
1469 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1471 --- 1.8.4 2002/01/04
1473 Scan for ZOOM API. New object ZOOM_scanset. New functions
1474 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1475 ZOOM_scanset_destroy.
1477 New ZOOM function, ZOOM_connection_last_event, that returns type
1478 of last event (such as "receive data", "send data", "apdu received",
1481 New ZOOM option, schema, that specifies schema for retrieval.
1483 New CCL feature. Qualifiers can be aliases for one or more
1484 other qualifiers (if more than one is given, OR is used).
1486 ZOOM uses named result sets if target supports it.
1488 Two new YAZ client commands: . (dot, which sources a script of YAZ
1489 client commands), and ! (to execute shell command.). Implemented
1492 Working on Debian packages.
1494 --- 1.8.3 2001/11/19
1496 YAZ client enables named result sets only if target supports it.
1498 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1500 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1501 with key="host" to get same result.
1503 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1504 Function Z3950_resultset_record(s) returns references to records
1505 "owned" by resultset. To become owner use Z3950_record_clone.
1507 Function z_ext_record handles Extended Services. Thanks to
1510 --- 1.8.2 2001/11/12
1512 CCL Parser fix: ignore token comma when dealing with and-lists.
1514 Documentation updates for COMSTACK.
1516 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1517 Changed prototype Z3950_records. For some functions, int parameters
1518 were changed to size_t.
1520 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1523 New MARC decode/display function, marc_display_exl, which properly rejects
1524 non-ISO2709 records. YAZ client uses it.
1526 --- 1.8.1 2001/10/29
1528 Fix bug: local attribute set wasn't set correctly in PQF strings.
1532 * Old Z39.50 codecs no longer supported.
1534 Added ZOOM C binding. See http://zoom.z3950.org/
1536 Renamed states for COMSTACKs to avoid confusion with events.
1538 Implemented cs_look and proper cs_rcvconnect.
1540 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1542 Configure detects POSIX threads on OpenBSD.
1544 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1545 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1547 When error is returned from present handler, non-surrogate diagnostic
1548 is returned in present response (and fetch handler is no longer called).
1550 * Minor adjustments to pquery parser (PQF). Token characters may be
1551 escaped by using backslash (C-style).
1553 PQF parser allows string attribute values to be specified. For @attr,
1554 non-numeric characters after the equal-sign are treated as strings
1555 (e.g. @attr 9=title).
1557 CCL trunction character may be defined (@truncation in file)
1559 * function zget_ExtendedServicesRequest sets waitAction to
1560 waitIfPossible (was wait).
1562 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1565 CCL operator names may be set in field definition files (CCL_bibset).
1566 See ccl/bib1 for an example.
1568 Fixes in ASN.1 compiler for C++ compatibility.
1570 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1571 and "op_or" to avoid conflict with C++.
1573 Fixed problem with GNU readline detection on Redhat 7.0.
1575 Added step-size for Scan backend handler.
1577 Fixed bug that made the frontend server crash when no attribute
1578 set was specified for scan.
1580 Front-end server automatically switches to original working directory
1581 when installed as an NT service. Previously -w had to be specified to
1584 Added extended attributes for retrieval module (data1), so that data1
1585 records carry d1_readXML/SGML attributes. d1_read also supports
1586 null-data rules ( <tag/>)
1588 On UNIX when POSIX threads are available, a separate library libyazthread
1589 is created. Programmers should link with that library and the yaz library
1590 when using threads. The reason for the split was that some applications
1591 on Linux, such as Apache, doesn't work well when using shared objects that
1594 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1595 (or any frontend server) in SSL mode by specifying ssl: followed by
1596 address. Only tested on UNIX.
1598 Added feature for CCL module. Virtual structure s=al or s=ol generates
1599 and-list and or-list respectively instead of phrase search.
1603 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1604 log_mask_str. This was done to avoid name conflicts with other libraries
1605 (such as other PHP extensions).
1607 Added raw OID member for preferred record syntax (request_format_raw)
1608 and returned record syntax (output_format_raw) for backend fetch method.
1610 Config file yaz-config now accepts options so that it returns specific
1611 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1613 Shared library support for UNIX using GNU libtool.
1615 * Modified backend interface. Request/Response struct's replaced by
1616 one read/write C struct. For example bend_fetchrequest and
1617 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1618 Every handler - even search has to be registered in bend_init
1619 handler. This means that the YAZ library no longer refers to
1620 external functions and it makes it possible to make the whole
1621 thing a single DLL/SO.
1623 Added Segment handler for backend server.
1625 Added Zmbol/Zebra administrative functions to YAZ client.
1627 Threaded frontend server on UNIX (when POSIX Threads are available).
1628 Starting the server with option -T enables multi-threading.
1632 Added configure option --enable-comp/disable-comp to control use
1633 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1634 located in sub directory asn.
1636 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1637 in ${exec_prefix}/bin along with the other programs yaz-client and
1640 GNU automake used to maintain makefiles.
1642 Added several OID's.
1644 Changed retrieval module so that we can load records with no abstract
1645 syntax defined. Tagpaths in these records are fully composed of string
1648 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1652 On UNIX, the generated makefile now supports a proper 'make install'.
1653 The prefix can be set via GNU configure to set the install location
1654 (default is /usr/local).
1656 * YAZ programs client and ztest were renamed to yaz-client and
1657 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1658 locations, such as /usr/bin,/usr/local/bin,etc.
1660 * YAZ Header files were moved from include to include/yaz. YAZ Header
1661 files are referred to as include <yaz/log.h> rather than <log.h>.
1662 The YAZ include path (-I ..) is therefore the same as before. Programmers
1663 should update their #include statements or use -Ipath/include/yaz
1664 instead. The main motivation for doing this change is that YAZ header files
1665 can be installed in "standard" locations /usr/include,/usr/local/include
1666 without introducing conflicts, since ALL YAZ header files are stored
1667 in subdirectory yaz (under /usr/include for example).
1669 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1670 rather than project/workspace files. We switched because project files
1671 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1674 Changed name of logging function, logf, to yaz_log, to prevent name
1675 clash with some math-log functions. The YAZ header log.h defines logf
1676 to yaz_log (#define) so there should be no incompatibilities by this
1679 Added bend_start/bend_stop handlers for server. These handler are
1680 called on start/stop of server. For windows they are called whenever
1681 a service is started/stopped.
1683 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1684 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1685 in util/yc.tcl. The auto-generated C code structures are, in a few
1686 cases, incompatible with the old decoders. There are differences in the
1687 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1688 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1689 The preprocessor variable ASN_COMPILED is defined when the compiled
1690 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1691 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1692 wish to use the old encoders/decoders you can specify --disable-yc
1695 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1696 version so that it supports both new - and old version of DB Update
1698 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1699 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1700 change. The name parameter can be set to 0 in which no name is specified
1701 for the construction. The macros odr_implicit and odr_explicit sets name
1702 parameter to zero for the construction involved. New macros
1703 odr_implicit_tag and odr_explicit_tag are similar to the others,
1704 except that a name parameter is added. For programmers' that don't use
1705 ODR they probably only need to change the call to z_APDU and z_External.
1707 Added access control facility by interfacing the TCP wrapper library.
1708 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1709 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1710 name of the daemon and enables the access control as specified in
1711 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1713 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1714 den Dool <H.M.vdnDool@kub.nl>.
1716 Added reference ID parameter to most functions in server API - refer
1717 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1719 Changed name of ccl library to libccl.a (was ccl.a).
1721 Fixed bug in decoder for Explain (Category TargetInfo).
1723 Added support for GNU readline in client. Thanks to Jacob Poulsen
1724 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1726 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1727 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1728 IMPLEMENTATION! This change was made to the development version before
1729 the ZIG decided to retract the amendment. If any users MUST be
1730 compatible with the original Update definition, PLEASE CONTACT US, and
1731 we will include a separate definition corresponding to the old Update
1732 ES. Note that because of the change to the ASN.1 of the
1733 TaskPackageRecordStructure we cannot define a single structure that
1734 will support both versions.
1736 * Added const modifier to buffer parameter for some ODR/BER encoding
1737 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1738 completeWAIS, odr_dumpBER.
1740 Fixed bug in client.c which caused a crash when a scanResponse didn't
1741 contain positionOfTerm.
1743 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1744 * will cause an error in a client if a non-YAZ target sends both a
1745 * list of Scan entries and non-surrogate diagnostics.
1747 Retrieval module enhancements. Tag sets may be typed in the reference
1748 to it. From the .abs-file the "tagset" directive takes a third optional
1749 integer type for the tag set referenced. From a .tag-file the "include"
1750 directive takes a third optional type as well. The old "type" directive
1751 in the tag set itself is still recognized but acts as the default type
1754 Backend interface change. Individual Scan terms returned from bend_scan
1755 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1756 in include/backend.h.
1758 Retrieval module enhancements. Multiple tag sets and attribute sets may
1759 be specified in abstract syntax specs. Revised the error/warning for
1760 logging messages reported by the retrieval module when reading the
1763 Object Identifier system (oid_..) changed. The API is backwards
1764 compatible but the oid-routines now allocates new OID's when needed.
1765 Raw OID's may be specified in oid_getvalbyname.
1767 YAZ now uses GNU configure to generate Makefile(s).
1769 * Minor changes in some of the member names of DeleteResultSetRequest and
1770 DeleteResultSetResponse. See include/proto.h.
1772 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1773 and added member 'languages' in TargetInfo (which was missing).
1775 Changed the way attribute sets are handled in the retrieval
1776 module. These are now cached, just like the abstract syntaxes
1779 Changed YAZ so that it links with compiled ASN.1.
1781 Added Explain-schema definitions and mapping routines. The following
1782 Explain categories have been implemented: AttributeDetails,
1783 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1785 Fixed minor bug in Windows version of Server Library.
1787 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1789 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1791 Added EXTERNAL: UNIverse Resource Report (non-standard).
1793 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1794 ENUMERATED and SET OF.
1796 * Added 'const' to some of the char pointer arguments for the
1797 functions, data1_read_node, data1_getelementbytagname,
1798 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1801 Fixed bug in data1_insert_taggeddata - the last_child member of
1802 parent wasn't initialised.
1804 * Changed data1_read_record and data1_read_node so that the supplied
1805 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1806 doesn't refer to any parts of the "SGML"-buffer.
1808 Fixed bug in server library (Windows version of statserv_remove).
1810 * Changed code so that it compiles as C++. The type definition
1811 of Odr_fun which is a member of Odr_arm was changed. The result is,
1812 that an explicit typecast is needed for the fun pointer when
1813 using Odr_arm - as in:
1814 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1816 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1818 Implemented the new structured date and time definition as approved
1819 by the ZIG. Added schemaId element to the specificTag in Espec-1
1820 (also approved at the last ZIG). Thanks to RVDM.
1822 Added some Object identifiers (RVDM).
1824 Changed the Update Extended Service (RVDM).
1826 Added command "refid" to client which specifies referenceId for
1827 the following requests.
1829 Implemented extended service handling for server. See ztest.c
1830 for an example as well as backend.h. New handlers are registerd
1831 in the Init handler.
1833 * Changed interface for sort in server.
1835 Added new members to statserv_options_block. It allows a server
1836 to read options from another source than just the command line. Thanks
1837 to Charles Woodfield.
1839 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1840 renamed to zboolean. Some C++ compilers complained about the name.
1842 Minor changes to gils.abs. Added index 's' (sort) on title
1843 and date/time-last-modified.
1845 --- 1.4pl2 1998/1/30
1847 Fixed bug in server library regarding inetd mode (-i). This bug
1848 was introduced by release 1.4.
1850 --- 1.4pl1 1998/1/29
1852 Added sort facility in client and backend server interface.
1854 Fixed problem with dependencies in Makefile(s).
1856 Fixed bugs for encoders/decoders of extended services and
1859 Implemented sub-tree feature for schemas. Sub-trees are
1860 referenced in *.abs-files. See explain.abs for an example
1861 of the use of this feature.
1863 Modified bib1.att; local attributes for ANY didn't include
1864 ANY itself (only affects use of the retrieval module).
1866 Fixed bug in plain SGML reader in function data1_read_node:
1867 tags with prefix "var" was incorrectly interpreted as variants.
1869 Added feature "sub-schemas" to enable references to - and definitions
1870 of - group of elements.
1872 * Removed member parent from type data1_element (in data1.h).
1874 Implemented function odr_nullval() that returns the value of
1877 * Removed member num_children from data1_node (in data1.h).
1879 Made NT service interface part of the server library. The
1880 function statserv_main uses the NT service when required and
1881 calls the statserv_start / statserv_close routines.
1883 Routine zget_SearchRequest and zget_PresentRequest fills
1884 resultSetName/Id member with "default" instead of "Default".
1886 Fixed memory leak in server. Request queue member wasn't freed.
1888 Fixed nmem_exit so that memory is freed.
1892 Revised the CCL parser utility to be thread safe.
1894 Added function, oid_ent_to_oid, to replace the function
1895 oid_getoidbyent, which is not thread safe.
1897 * Added nmem_init and nmem_exit to initialize and release
1898 NMEM resources. Function nmem_init should be called once in the
1899 initial thread before NMEM/ODR is used. statserv.c and client.c
1900 have been changed accordingly. The change was necessary to make
1901 NMEM thread safe. The NMEM memory pool is shared amongst threads
1902 in a process. Unix-based applications will still work fine without
1905 Added NT Services interface for the the Z39.50 (statserv) Server.
1906 Refer to the ztest.c source on the usage.
1908 Windows 95/NT port using MSVC5.0. Project files are included in the
1911 * Defined new 'global' handle for the retrieval (data1) system. The
1912 new handled, data1_handle, describes the state of the data1 system.
1913 This handle is passed as first argument to virtually all
1914 data1 related routines. The functions data1_create and data1_destroy
1915 creates and destroys a data1 handle respectively.
1917 Added ODR encode stream member to all backend request structures
1918 init, search, scan etc. This stream should be used to allocate all
1919 memory used for the response when thread safe operation is needed.
1921 Changed the comstack utility, cs_addstr, to be thread safe. The
1922 returned hostname string returned by the function is now part the
1925 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1926 function. The cs_straddr takes a COMSTACK handle as argument, so this
1927 function must be used after cs_create and before bind/connect.
1928 This function is thread safe.
1930 Moved test server to 'ztest' directory - generic server code still
1931 in 'server' directory.
1933 Made prefix query (pquery.c) utility thread safe.
1935 Added new function modifier YAZ_EXPORT to 'export' public DLL
1936 functions when using windows (see include/yconfig.h).
1938 Added definitions to the OID database (util/oid.c) (RVDM).
1940 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1942 Added call to ccl_rpn_delete in client program.
1944 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1945 release of RPN structure.
1947 Added support for C++, headers uses extern "C" for public definitions.
1948 With input from RVDM.
1950 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1951 Thanks to Ronald van der Meer (RVDM).
1953 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1955 Added support for private extensions to the OID database
1956 (oid_setprivateoids()). Thanks to RVDM.
1958 Added optional, physical ANY (key replication)
1960 Fixed null-reference problem in GRS-1 output filter.
1962 Proximity operator added to Prefix Query Format (PQF).
1964 In test client command "base" accepts multiple databases.
1966 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1970 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1972 Smallish bug-fixes in the new encoders/decoders (explain).
1974 Bug fixed in DeleteRequest.
1976 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1978 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1980 Added SOIF syntax (using private OID for now) to retrieval module and client.
1982 Added Update extended service.
1984 Added SearchResult-1 additional info structure.
1986 Added optional CCL (ISO8777) interpreter as separate module. Available
1989 --- 1.2 1996/6/10 (1st anniversary release)
1991 Added Summary record syntax. Lightly tested.
1993 Added OPAC record syntax. Untested.
1995 Added ResourceReport service encoders/decoders. Untested.
1997 Fixed bug in z_Unit - wrong tagging on unitSystem.
1999 Fixed bug in the DiagRecs decoder.
2001 Added options for max PDU size and session timeout to frontend-server.
2003 Added documentation of query-language parsers and other supporting utilities.
2005 [frontend-server] Added Attribute set to the bend_scanrequest API.
2007 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2008 surrogate diagnostics were generated.
2010 [retrieval] Allow multiple local values for attribute.
2012 [retrieval] Allow multiple attributes per element in .abs files. index type.
2014 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2016 --- 1.1pl2 1996/4/10
2018 Minor changes, mostly specific to Zebra's requirements (retrieval)
2022 Repaired bug in frontend server when running multiple listening
2023 endpoints in dynamic mode.
2025 z_External() now won't break if a known, ASN.1 value comes encapsulated
2026 in an octet-string. The value will pass through unmodified in an Odr_oct.
2028 Added a bit of code to the demo client to decode & display
2029 ASN.1-structured records represented in the octet-aligned branch of
2030 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2032 Added z_ext_getentbyref() to the ASN module. Doc updated.
2034 * Completed the SCAN definition in the ASN module. This may break SCAN
2035 code based on older YAZ-versions at compile-time. The fix is easy -
2038 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2039 under the SCAN definition. Remember to initialize this, server-people.
2041 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2042 that this does not extend to ODR and ASN.
2044 Comstack allows insertion of established socket (primarily for
2045 inetd-operation of servers). Doc updated.
2047 Front-end server can now start from the inetd in TCP mode. Doc
2050 --- 1.0pl4 1996/1/24
2054 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2055 the rank and record number.
2057 Adjustments to the frontend server.
2059 Fixed diagnostic BER dumper. It ignored the file argument.
2063 Various changes to retrieval module.
2065 Changed the union discriminators of the protocol files from enums to
2066 ints paired with #defines.
2068 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2071 *Changed operator in the RPN structure to 'roperator', again to avoid a
2074 Fixed problems in Explain decoders/encoders.
2076 --- 1.0pl2 1995/12/6
2078 Memory bug in log module fixed.
2080 --- 1.0pl1 1995/12/5
2082 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2084 Bug in Explain DatabaseInfo module fixed.
2086 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2090 The shift to v1.0 signals that we now consider the *core* functionality
2091 of YAZ reasonably stable (the core being more or less equivalent to
2092 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2093 tested (Explain not at all - though that will happen soonish).
2095 Minor changes to code to support Windows port.
2097 Various minor changes after we're getting to use GRS-1 & co. more.
2099 Added Espec-1 format.
2101 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2102 of the protocol and it cannot be selected when encoding (maps into 'string'
2103 when decoding). Needed to talk to some servers.
2105 Demo client can request simple element set names.
2107 Added Diagnostic Format encoders/decoders.
2109 Added simple Close handling to frontend server (no hooks for resource
2110 reporting yet), and demonstration client.
2112 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2114 --- 1.0b3 1995/08/24
2116 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2117 handled incorrectly when records were requested in the searchResponse. This
2118 will only affect you if you use the frontend-server.
2120 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2121 Test-client will ask for and print GRS1. Ztest will return dummy records
2124 Added Explain encoders/decoders to the service-level API. Untested.
2126 Added Extended Services: Item Order encoders and decoders to the Service-
2127 level API. Untested. We could use a recent copy of the pertinent bits
2128 of the ILL protocol to add those bits.
2130 Added diagnostic format 1 encoders/decoders to the service-level API.
2133 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2134 odr_cons.c, which causes a more correct output.
2136 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2137 was always set to 0 when no records were requested in the searchRequest.
2139 * Added better external-handling. This shouldn't harm old code that
2140 *encodes* externals. It can break code that looks for a
2141 'single-ASN1-type' representation, since those types that are known
2142 are now decoded immediately. Look at the SUTRS sample code in
2143 seshigh.c and client.c. Documentation updated.
2145 Handling of structured records in bend_fetchresponse. Length -1 marks
2146 structured record, type is deduced from format field.
2148 --- 1.0b2 1995/06/27
2149 Fairly quick maintenance release to add SUTRS support.
2151 Fixed handling of SUTRS records in the demonstration client.
2153 * Added format field to the bend_fetchrequest and bend_fetchresponce
2154 structures of the backend API (frontend server). When the record is
2155 returned, the value of the format field is mapped to an OID. The
2156 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2157 of the record. The special value VAL_NONE in the bend_request means
2158 that no specific format was requested by the client. Documentation
2159 updated accordingly. Test server (ztest) will return a fixed dummy
2160 SUTRS record if your client requests SUTRS.
2162 Documentation updated accordingly.
2164 You can now set external libraries and RANLIB support in the top-level
2168 First public release.
